Brick Processing Manufacturer Wastewater Treatability

10.16.2009

The
Morin Brick Company sent a wastewater sample containing clay and sodium
silicate contaminants looking for a solution to removing these
contaminants from their wastewater. They manufacture bricks for
facilities in the Northeastern United States and Canada.

A 1,000ml beaker filled with the water sample was used to conduct the
treatability; the starting pH was recorded at 11.0. Floccin™ 1113 was
the recommended application for testing, where 6 grams was added to the
1,000ml beaker containing the wastewater. Flocculation occurred after
eight minutes of agitation to the treated sample and the pH dropped to
4.0. Approximately 1.0ml of 20% caustic was supplemented to increase
the pH to 7.0, where flocculation continued to hold.

Our conclusion was 40lbs of Floccin™ 1113 would be the required dosage for every 1,000 gallons of wastewater generated.

The
recommended wastewater pretreatment system would require an
equalization tank with pH adjustment and the wastewater is discharged
to a CFU-50 for dewatering. The Continuous Flow Unit comes equipped
with a Floccin™ Feeder to dispense Floccin™ 1113 into the treatment
tank where disposable filtering media is used for liquid/solid
separation and the effluent water is pumped to a sewer or water reuse
system.

Coagulation and flocculation are two main processes used to integrate colloidal particles into larger particles and are two main stages of primary water treatment. Coagulation and flocculation processes are only needed when colloidal particles are a significant part of the total suspended solid fraction. Our objective was to predict turbidity of water after the coagulation and flocculation process while other parameters such as types and concentrations of coagulants, pH, and influent turbidity of raw water were...

pH-sensitive copolymers have been widely introduced to achieve rapid dewatering and consolidation of solids in mining and oil sands processing wastes. But no more attention has been given to the flocculation efficiency of solid suspensions as a function of pH using pH-sensitive copolymer. In this study, a pH-sensitive copolymer was synthesized and employed to investigate the flocculation behaviors of kaolin by focused beam reflectance measurement (FBRM). A titration test was introduced to characterize the copolymer...

Problem
This factory had used multi disc type dewatering equipment for long time; however, they had been facing problems such as aging and lack of throughput of the equipment.
Due to a limited space for the dewatering equipment, they were looking for compact dewatering equipment with larger capacity.

In conventional treatment of variable quality mountain water, an inability to immediately adjust the coagulant dose to variations in water quality causes overdose or underdose of coagulant in relation to its optimal value. The results of the research showed that the reuse of post-coagulation sludge was an effective method to maintain high and stable coagulation effectiveness under both polyaluminium chloride (PACl) overdose and underdose conditions. Recycled sludge contains a large portion of insoluble aluminium...

Chitosan was chosen as an alternative primary coagulant in a complementary coagulation–flocculation treatment of sanitary landfill leachate with the aim of removing recalcitrant organic matter. In order to optimize the process conditions, central composite design and response surface methodology were applied. To evaluate the performance of the process using chitosan, we also carried out tests with aluminium sulphate (Al2 (SO4)3.14 H2O) as coagulant. In addition, acute toxicity tests were carried using the...
